Sichuan Keenlion Microwave Technology——lub tshuab faib hluav taws xob
Sichuan Keenlion Microwave Technology Tau tsim muaj xyoo 2004, Sichuan Keenlion Mircrowave techenology CO., Ltd. yog lub chaw tsim khoom ua ntej ntawm cov khoom siv Passive Mircrowave hauv Sichuan Chengdu, Suav.
Peb muab cov khoom siv mirrowave ua haujlwm tau zoo thiab cov kev pabcuam cuam tshuam rau kev siv microwave hauv tsev thiab txawv teb chaws. Cov khoom lag luam pheej yig, suav nrog ntau yam khoom faib hluav taws xob, cov khoom sib txuas lus, cov lim dej, cov khoom sib txuas, cov khoom duplexer, cov khoom sib cais ua haujlwm, cov khoom cais thiab cov khoom sib xyaw. Peb cov khoom lag luam tau tsim tshwj xeeb rau ntau qhov chaw ib puag ncig thiab qhov kub thiab txias. Cov lus qhia tuaj yeem tsim raws li cov neeg siv khoom xav tau thiab siv tau rau txhua qhov zaus txheem thiab nrov nrog ntau yam bandwidths los ntawm DC txog 50GHz.
lub tshuab faib hluav taws xob

Lub tshuab faib hluav taws xobyog ib lub cuab yeej uas faib ib lub zog teeb liab nkag mus rau hauv ob lossis ntau txoj kab thiab tso tawm lub zog sib npaug lossis tsis sib npaug. Nyob rau hauv lem, nws tuaj yeem ua ntau lub zog teeb liab rau hauv ib qho tso zis. Lub sijhawm no, nws kuj tseem tuaj yeem hu ua combiner.

Yuav tsum muaj qee qib kev sib cais ntawm cov qhov tso zis ntawm lub zog faib hluav taws xob. Lub zog faib hluav taws xob tseem hu ua over-current distributor, uas muab faib ua active thiab passive. Nws tuaj yeem faib ib lub teeb liab mus rau ntau qhov tso zis. Feem ntau, txhua lub sub channel muaj ntau dB attenuation. Qhov attenuation ntawm cov faib hluav taws xob sib txawv kuj txawv vim muaj ntau zaus teeb liab. Yuav kom them rau qhov attenuation, lub zog faib hluav taws xob passive yog ua tom qab ntxiv lub amplifier.

Kev taw qhia txog kev ua haujlwm

Lub luag haujlwm ntawm lub tshuab faib hluav taws xob yog faib cov teeb liab los ntawm ib txoj kab sib npaug rau ntau txoj kab rau cov zis, feem ntau suav nrog ob lub zog faib, plaub lub zog faib, rau lub zog faib thiab lwm yam. Kev siv thiab kev ua tau zoo ntawm peb lub cuab yeej saum toj no txawv kiag li, tab sis nws feem ntau yooj yim rau kev tsis meej pem lub npe hauv kev siv txhua hnub, uas ua rau tib neeg tsis meej pem hauv kev siv. Ntau lub satellite receivers hauv lub satellite TV txais system sib koom ib lub antenna, ntau lub antennas sib koom ib lub satellite receiver, thiab ntau dua ob lub satellite receivers thiab ntau dua ob lub antennas sib koom. Ntxiv rau cov cables, kev sib txuas ntawm lawv feem ntau yog pom los ntawm kev sib xyaw ua ke.

kev tsim cov switchers. Lub tshuab faib hluav taws xob siv los txuas ntau lub satellite receivers. Yog tias yuav tsum txuas ib pawg antennas rau ntau lub satellite receivers, yuav tsum siv lub tshuab faib hluav taws xob. Xaiv lub tshuab faib hluav taws xob raws li tus naj npawb ntawm cov receivers txuas nrog. Yog tias ob lub receivers txuas nrog, siv ob lub tshuab faib hluav taws xob. Txuas plaub lub receivers thiab siv plaub lub tshuab faib hluav taws xob.

Cov cim qhia txog kev siv tshuab

Cov ntsuas kev siv tshuab ntawm cov khoom faib hluav taws xob suav nrog ntau zaus, lub zog nqa, kev faib tawm poob ntawm lub voj voog tseem ceeb mus rau ceg, kev nkag poob ntawm cov tswv yim thiab cov zis, kev sib cais ntawm cov chaw nres nkoj ceg, qhov sib piv ntawm cov hluav taws xob sawv ntsug ntawm txhua qhov chaw nres nkoj, thiab lwm yam.

1. Qhov ntau zaus. Qhov no yog qhov ua haujlwm ntawm ntau yam RF / microwave circuits. Cov qauv tsim ntawm lub zog faib hluav taws xob muaj feem cuam tshuam nrog qhov zaus ua haujlwm. Qhov zaus ua haujlwm ntawm lub zog faib hluav taws xob yuav tsum tau txhais ua ntej qhov kev tsim qauv hauv qab no tuaj yeem ua tiav.

2. Tiv taus lub zog. Hauv lub tshuab faib hluav taws xob / tshuab ua kom muaj zog siab, lub zog siab tshaj plaws uas cov khoom sib xyaw ntawm lub voj voog tuaj yeem ris tau yog qhov ntsuas tseem ceeb, uas txiav txim siab seb hom kab xa hluav taws xob twg tuaj yeem siv los ua tiav txoj haujlwm tsim. Feem ntau, qhov kev txiav txim ntawm lub zog uas kab xa hluav taws xob nqa los ntawm me mus rau loj yog kab microstrip, kab stripline, kab coaxial, kab air stripline thiab kab air coaxial. Yuav tsum xaiv kab twg raws li txoj haujlwm tsim.

3. Faib cov kev poob. Qhov kev poob ntawm kev faib tawm ntawm lub voj voog tseem ceeb mus rau lub voj voog ceg yog qhov tseem ceeb cuam tshuam nrog qhov piv ntawm kev faib hluav taws xob ntawm tus neeg faib hluav taws xob. Piv txwv li, qhov kev poob ntawm kev faib tawm ntawm ob lub faib hluav taws xob sib npaug yog 3dB thiab ntawm plaub lub faib hluav taws xob sib npaug yog 6dB.

4. Kev poob ntawm kev ntxig. Qhov kev poob ntawm kev ntxig ntawm cov khoom nkag thiab cov zis yog tshwm sim los ntawm qhov nruab nrab tsis zoo lossis tus neeg coj ntawm txoj kab xa xov (xws li txoj kab microstrip), xav txog qhov kev poob los ntawm qhov piv ntawm nthwv dej sawv ntawm qhov nkag.

5. Kev rho tawm. Kev rho tawm ntawm cov chaw nres nkoj ceg yog lwm qhov tseem ceeb ntawm kev faib hluav taws xob. Yog tias lub zog nkag los ntawm txhua qhov chaw nres nkoj ceg tsuas yog tuaj yeem tso tawm los ntawm qhov chaw nres nkoj tseem ceeb thiab yuav tsum tsis txhob tso tawm los ntawm lwm ceg, nws yuav tsum muaj kev rho tawm txaus ntawm cov ceg.

6. Qhov piv ntawm nthwv dej sawv ntsug. Qhov me dua VSWR ntawm txhua qhov chaw nres nkoj, qhov zoo dua.

Lublub tshuab faib hluav taws xobmuaj peev xwm muab faib ua ob pawg raws li qhov kev teeb tsa:

(1) Cov yam ntxwv tseem ceeb ntawm passive power divider yog: kev ua haujlwm ruaj khov, cov qauv yooj yim thiab tsis muaj suab nrov; Nws qhov tsis zoo tseem ceeb yog tias qhov poob nkag loj dhau.

(2) Lub tshuab faib fais fab nquag yog tsim los ntawm lub amplifier. Nws cov yam ntxwv tseem ceeb yog: nce thiab kev rho tawm siab. Nws cov teeb meem tseem ceeb yog suab nrov, cov qauv nyuaj thiab kev ua haujlwm tsis ruaj khov. Lub qhov tso zis ntawm lub tshuab faib fais fab muaj ob lub zog, peb lub zog, plaub lub zog, rau lub zog, yim lub zog thiab kaum ob lub zog.

Lub npe tag nrho ntawm lub tshuab faib fais fab yog lub tshuab faib fais fab. Nws yog ib lub cuab yeej uas faib ib lub zog ntawm lub teeb liab nkag mus rau hauv ob lossis ntau txoj kab thiab tso tawm lub zog sib npaug lossis tsis sib npaug. Tom qab ntawd, nws tuaj yeem tsim ntau lub zog ntawm lub teeb liab ua ib qho zis. Lub sijhawm no, nws kuj tseem hu ua combiner. Yuav tsum muaj qee qib kev sib cais ntawm cov qhov tso zis ntawm lub tshuab faib fais fab. Raws li cov zis, lub tshuab faib fais fab feem ntau muab faib ua ib mus rau ob (ib qho nkag thiab ob qho tso zis), ib mus rau peb (ib qho nkag thiab peb qhov tso zis), thiab lwm yam. Cov kev cai tseem ceeb ntawm lub tshuab faib fais fab suav nrog kev poob zog (xws li kev poob ntawm kev ntxig, kev poob ntawm kev faib tawm thiab kev poob ntawm kev cuam tshuam), qhov sib piv ntawm lub zog sawv ntsug ntawm txhua qhov chaw nres nkoj, kev sib cais ntawm cov chaw nres nkoj faib fais fab, qhov sib npaug ntawm qhov siab, qhov sib npaug ntawm theem, lub peev xwm fais fab thiab qhov dav ntawm cov zaus.

Peb kuj tseem tuaj yeem kho cov khoom siv rf passive raws li koj xav tau. Koj tuaj yeem nkag mus rau nplooj ntawv kho kom raug kom muab cov lus qhia koj xav tau.
